We've been waiting to see Britney Spears' commercial for the new Twister Dance ever since we saw her RAWKING that $20,000 bra during the shoot back in April, and now, the final version has arrived in all of its FEROCITY!

And believe us, it is NOT to be missed!

Ch-ch-check out the pop sensation showing off some serious moves as she belts out her smash single, 'Till The World Ends (above)!

AGH! She looks INCREDIBLE!

And we LOVE that Twister was able to amp up all the fun of the original game and make it more cardio-friendly!

Now excuse us! We have to go shake our booty to this on loop for the rest of the day!
